No, you can see objects and things even when it is not light outside. Our ability to see relies on the presence of light, but that light can come from various sources, not just the Sun. Here are a few scenarios where visibility is possible even when it is not light outside:
Artificial Lighting: Indoor environments, such as homes, offices, or public spaces, are typically illuminated by artificial light sources like lamps, ceiling lights, or light fixtures. These artificial light sources allow us to see and perceive objects even when it is dark outside.
Moonlight: The Moon reflects sunlight and provides a certain level of illumination during nighttime. Moonlight can be sufficient for us to see and navigate in many situations, especially in open areas with minimal light pollution.
Streetlights and Outdoor Lighting: Many urban areas have streetlights and outdoor lighting installed for visibility and safety purposes. These lights provide illumination during the night, making it possible to see objects and surroundings.
Bioluminescence: Some organisms, such as certain types of marine life, emit their own light through a process called bioluminescence. This light emission can be visible in dark environments, such as underwater or in deep caves.
Infrared and Night Vision Technology: Certain technologies, such as infrared cameras or night vision devices, can detect and amplify low levels of light that are not visible to the naked eye. These technologies allow for enhanced visibility in low-light or dark conditions.
It's important to note that while visibility is possible in low-light or dark conditions with the aid of artificial light sources or other means, our visual perception may be different compared to well-lit environments. Our eyes are adapted to function optimally in various lighting conditions, but they have limitations in extreme darkness or absence of light.
